A clinical risk score for the prediction of very late stent thrombosis in drug eluting stent patients.

Aims: Very late stent thrombosis (VLST; >1 year) is an infrequent but potentially serious complication, whose risk factors have not been fully elucidated. This investigation sought to develop a clinically useful risk stratification score for VLST following drug eluting stent (DES) placement.

Methods And Results: A Cox proportional hazards multivariate model of VLST was developed based on follow-up into a second year of patients enrolled in the ARRIVE registries, utilising readily available baseline clinical and angiographic characteristics.

One-year outcomes from the TAXUS express stent versus cypher stent.

We compared 1-year outcomes in patients treated with paclitaxel-eluting stents (PESs) or sirolimus-eluting stents (SESs) in "real-world" clinical practice. Clinical outcomes were evaluated in 1,558 consecutive, unselected, retrospectively collected patients treated with drug-eluting stents (DESs; PES = 816, SES = 742) at 19 United States centers. The primary end point was 1-year target vessel revascularization (TVR).

A clinical risk score for prediction of stent thrombosis.

The aim was to develop a clinically useful patient risk score predictive for stent thrombosis (ST). Using readily available baseline clinical and angiographic characteristics, a Cox proportional hazards multivariate model was used to identify significant (p <0.10) predictors of ST through 1 year in 2,487 patients receiving a TAXUS Express (Boston Scientific Corp.
